TECHNICAL FIELD

The disclosure relates to the field of communication, and more particularly to a data transmission method, a network device and a terminal device.

BACKGROUND

In an existing Long Term Evolution (LTE) system, all resources for data transmission are allocated based on a same subcarrier spacing, which is unable to meet a multiplexing requirement of different subcarriers in a 5th-Generation (5G) system.

SUMMARY

In view of this, the disclosure provide a data transmission method, a network device and a terminal device, which may enable the same terminal device to perform transmission of data by use of resources with different subcarrier spacings in a scheduling unit.

A first aspect provides a data transmission method, which may include the following operations. Resource configuration information is sent to a terminal device. The resource configuration information is configured to indicate multiple resource sub-bands for transmitting data in a scheduling unit, each of the multiple resource sub-bands is formed by continuous physical resource blocks on a frequency domain and at least two resource sub-bands in the multiple resource sub-bands have different subcarrier spacings. The data is communicated with the terminal device on the multiple resource sub-bands.

The scheduling unit may indicate one or more resource blocks with a certain width in the frequency domain, and is not limited in a time domain. The frequency-domain scheduling unit may occupy the whole system bandwidth and may also occupy part of the system bandwidth, and a minimum width of the frequency-domain scheduling unit is a basic physical resource block.

The resource sub-band may be formed by continuous physical resource blocks with the same frequency-domain width, and may also be formed by discontinuous physical resource blocks with the same frequency-domain width.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the disclosure.

It is to be understood that the technical solutions of the embodiments of the disclosure may be applied to various communication systems, for example, a Global System of Mobile Communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system or a future 5G system.

Particularly, the technical solutions of the embodiments of the disclosure may be applied to various nonorthogonal multiple access technology-based communication systems, for example, a Sparse Code Multiple Access (SCMA) system and a Low Density Signature (LDS) system, and of course, the SCMA system and the LDS system may also have other names in the field of communication. Furthermore, the technical solutions of the embodiments of the disclosure may be applied to multi-carrier transmission systems adopting nonorthogonal multiple access technologies, for example, Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multi-Carrier (FBMC), Generalized Frequency Division Multiplexing (GFDM) and Filtered-OFDM (F-OFDM) systems adopting the nonorthogonal multiple access technologies.

In the embodiments of the disclosure, a terminal device may indicate User Equipment (UE), an access terminal, a user unit, a user station, a mobile station, a mobile radio station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The access terminal may be a cell phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Localized Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with a wireless communication function, a computing device or another processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, a terminal device in a future evolved Public Land Mobile Network (PLMN) or the like. There are no limits made in the embodiments of the disclosure.

In the embodiments of the disclosure, a network device may be a device configured to communicate with the terminal device. The network device may be a Base Transceiver Station (BTS) in the GSM or the CDMA, may also be a NodeB (NB) in the WCDMA system, may also be an Evolutional Node B (eNB or eNodeB) in the LTE system and may further be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. Alternatively, the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in the future 5G network, a network device in the future evolved PLMN or the like. There are no limits made in the embodiments of the disclosure.

FIG. 1 is a schematic diagram of an application scenario according to an embodiment of the disclosure. A communication system in FIG. 1 may include a terminal device 10 and a network device 20. The network device 20 is configured to provide communication service for the terminal device 10 and access a core network. The terminal device 10 searches a synchronization signal, broadcast signal and the like sent by the network device 20 to access the network, thereby communicating with the network. Arrows illustrated in FIG. 1 may represent uplink/downlink transmission implemented through a cellular link between the terminal device 10 and the network device 20.

Along with constant evolution of communication technologies, diversified service types are required in a future communication system, and a single subcarrier spacing in an LTE system may not meet a communication requirement. Unlike the LTE system, in a future wireless communication system such as 5G multiple numerologies may coexist in a manner of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM) or combination of the two in a carrier/cell/wireless Transmit Receive Point (TRP), to keep flexibility and forward compatibility of the system. Different numerologies usually adopt different carrier spacings, and resources with different subcarrier spacings may also be allocated for the same terminal in the same scheduling unit. However, an existing resource allocation method based on the same subcarrier spacing in the LTE system may not meet this requirement.

FIG. 2 is a schematic block diagram of a data transmission method 100 according to an embodiment of the disclosure. As illustrated in FIG. 2, the method 100 may be executed by a network device and, for example, may be executed by a base station. The method 100 includes the following operations.

In S110, resource configuration information is sent to a terminal device, the resource configuration information is configured to indicate multiple resource sub-bands for transmitting data in a scheduling unit, each of the multiple resource sub-bands is formed by continuous physical resource blocks in a frequency domain and at least two resource sub-bands in the multiple resource sub-bands have different subcarrier spacings.

In S120, the data is communicated with the terminal device on the multiple resource sub-bands.

Specifically, the network device divides the whole scheduling unit into the multiple resource sub-bands according to multiple subcarrier spacings preconfigured by a system, each resource sub-band is formed by continuous physical resource blocks in the frequency domain, and at least two resource sub-bands adopt different subcarrier spacings, which specifically refers to FIG. 3. As illustrated in FIG. 3, assume that two resource sub-bands, i.e., a first resource sub-band and a second resource sub-band, are configured for the terminal device in a scheduling unit, the first resource sub-band may be formed by multiple continuous physical resource blocks illustrated in FIG. 3, and the second resource sub-band is also formed by multiple continuous physical resource blocks illustrated in FIG. 3. The physical resource blocks forming the first resource sub-band and the physical resource blocks forming the second resource sub-band have different frequency-domain widths. For example, the frequency-domain width of the physical resource blocks forming the first resource sub-band may be 45 kHz. and the frequency-domain width of the physical resource blocks forming the second resource sub-band may be 30 kHz.

It is to be understood that the scheduling unit may indicate one or more resource blocks with a certain width in the frequency domain, and is not limited in a time domain. The frequency-domain scheduling unit may occupy the whole system bandwidth and may also occupy part of the system bandwidth, and a minimum width of the frequency-domain scheduling unit is a basic physical resource block.

It is also to be understood that the data may indicate uplink data, namely the terminal device may send the data to the network device through the multiple resource sub-bands allocated by the network device, and may also indicate downlink data, namely the network device may also send the data to the terminal device through the multiple resource sub-bands allocated by the network device. There are no limits made thereto in the embodiment of the disclosure.

According to the data transmission method provided in the embodiment of the disclosure, the resource sub-bands with different subcarrier spacings are divided in the scheduling unit to perform transmission of the data, so that localized continuous frequency-domain resources allocation with multiple attributes may be supported better.

In at least one embodiment of the disclosure, the resource configuration information includes first position indication information, and the first position indication information is configured to indicate a position of a first resource sub-band in the multiple resource sub-bands on the frequency domain.

Those skilled in the art knows that resource scheduling is required by transmission of the uplink data and transmission of the downlink data, that is, the network device is required to notify a system resource allocation process to the terminal device and then the terminal device may know about time and resources for data transmission or data reception. In a 5G system, the same terminal device is likely to send or receive data on resources with different subcarrier spacings, i.e., the resource sub-bands mentioned in the embodiment of the disclosure, in the scheduling unit, so that the resource configuration information sent to the terminal device by the network device includes a position of each resource sub-band on the frequency domain in the scheduling unit. For example, the resource configuration information sent to the terminal device by the network device includes two position indication information. The two position indication information indicate the positions of the first resource sub-band and second resource sub-band illustrated in FIG. 3 respectively, and may specifically indicate positions of multiple continuous physical resource blocks in the first resource sub-band on the frequency domain and positions of multiple continuous physical resource blocks in the second resource sub-band on the frequency domain.

In at least one embodiment of the disclosure, the first position indication information includes first indication information and second indication information. The first indication information is configured to indicate frequency-domain reference physical resource blocks including the first resource sub-band on the frequency domain in the scheduling unit, and a subcarrier spacing of each frequency-domain reference physical resource block is a multiple of a maximum subcarrier spacing preconfigured by a system. The second indication information is specifically configured to indicate positions of the physical resource blocks of the first resource sub-band in a starting frequency-domain reference physical resource block indicated by the first indication information and positions of the physical resource blocks of the first resource sub-band in an ending frequency-domain reference physical resource block indicated by the first indication information.

It is to be understood that the frequency-domain reference physical resource block may be a unit for virtually dividing the scheduling unit, and may also be a unit of resources actually allocated by a network device. For example, the network device, before sending the resource configuration information to the terminal device, may further notify frequency-domain widths of the frequency-domain reference physical resource blocks to the terminal device in a broadcast manner. The network device may allocate a resource block on the whole frequency domain of the scheduling unit, and the resource block is formed by multiple frequency-domain reference physical resource blocks. As illustrated in FIG. 4, the network device configures a resource block in a scheduling unit, the resource block is formed by three frequency-domain reference physical resource blocks, and a frequency-domain width of each frequency-domain reference physical resource block may be a maximum subcarrier spacing preconfigured by the whole system. For example, when subcarrier spacings preconfigured in the system include 15 kHz, 30 kHz, 60 kHz and 120 kHz, the network device may configure a resource block formed by multiple frequency-domain reference physical resource blocks, and a frequency-domain width of each frequency-domain reference physical resource block may be 120 kHz. The network device may also not actually divide the resource block formed by the frequency-domain reference physical resource blocks but directly divides the scheduling unit by a frequency-domain reference physical resource block. For example, a frequency-domain width of the virtual frequency-domain reference physical resource block may be 240 kHz.

It is to be understood that in the embodiment of the disclosure, the multiple resource sub-bands may include resources formed by all subcarrier spacings preconfigured in the system, and may also only include resources formed by part of the preconfigured subcarrier spacings. As described above, the network device may directly configure resource sub-bands formed by 15 kHz, 30 kHz, 60 kHz and 120 kHz for the terminal device, and may also only configure the resource sub-bands formed by 15 kHz and 30 kHz according to a requirement of the terminal device. The frequency-domain width of the frequency-domain reference physical resource block may be a multiple of the maximum subcarrier spacing in the system, and may also be more than or equal to the maximum subcarrier spacing adopted in the configured resource sub-bands. There are no limits made thereto in the disclosure.

A two-level resource indication manner may be adopted to determine the positions of the resource sub-bands in the frequency domain.

A resource indication of the first level may roughly indicate a configuration of the resource sub-bands in the frequency domain by use of the frequency-domain reference physical resource blocks. In at least one embodiment, a bit table is used, and a length of the bit table may be the total number of frequency-domain reference physical resource blocks in the present scheduling unit. Each bit in the bit table corresponds to a frequency-domain reference physical resource block. Specifically, a value 1 of each bit may indicate that the frequency-domain reference physical resource block includes resources of a certain resource sub-band, and otherwise, it does not include the resources. Assume that a scheduling unit includes four frequency-domain reference physical resource blocks. A bit table for indicating frequency-domain reference physical resource blocks including the first resource sub-band is 0111, it is indicated that a second frequency-domain reference physical resource block to fourth frequency-domain reference physical resource block in the whole scheduling unit include the resources of the first resource sub-band on the frequency domain. In another embodiment, a position of a frequency-domain reference physical resource block including a starting physical resource block of a certain resource sub-band in the frequency domain and a position of a frequency-domain reference physical resource block including an ending physical resource block of the resource sub-band in the frequency domain may also be indicated, or the position of the frequency-domain reference physical resource block including the starting physical resource block of a certain resource sub-band in the frequency domain and the number of all frequency-domain reference physical resource blocks including physical resource blocks of the resource sub-band may also be indicated. In other words, a pointer of a starting frequency-domain reference physical resource block including a certain resource sub-band and a pointer of an ending frequency-domain reference physical resource block including the resource sub-band may be included, or the pointer of the starting frequency-domain reference physical resource block including a certain resource sub-band and the number of frequency-domain reference physical resource blocks including the resource sub-band may be included. It is to be understood that, if a resource sub-band exists in only one frequency-domain reference physical resource block, a pointer of the frequency-domain reference physical resource block may be simply used for the indication of the first level.

A resource indication of the second level may further indicate the position of the resource sub-band on the frequency domain by use of the positions of the physical resource blocks of the resource sub-band in the corresponding frequency-domain reference physical resource blocks. Specifically, a position of a starting physical resource block allocated for a certain resource sub-band in a starting frequency-domain reference physical resource block and a position of an ending physical resource block allocated for the resource sub-band in an ending frequency-domain reference physical resource block are included. For example, if a frequency-domain reference physical resource block includes eight physical resource blocks of a certain resource sub-band, a position of a starting physical resource block in the starting frequency-domain reference physical resource block may be any of positions 1-8, and namely may be represented by three bits. Similarly, a position of an ending physical resource block in the ending frequency-domain reference physical resource block may also be represented by three bits.

In at least one embodiment, the positions of the physical resource blocks of a certain resource sub-band in the starting frequency-domain reference physical resource block and the positions of the physical resource blocks of the resource sub-band in the ending frequency-domain reference physical resource block may also be represented by two small bit tables respectively. Specifically, a length of each bit table is the number of the physical resource blocks of a certain resource sub-band in a frequency-domain reference physical resource block. A bit having a value 1 indicates that the physical resource block corresponding to the bit belongs to the resource sub-band.

It is to be understood that the values of the bit tables and the two-level resource indication manner are only exemplarily described for convenient understanding and not intended to limit the embodiment of the disclosure.

In at least one embodiment of the disclosure, when resource sub-bands are located in non-overlapped frequency-domain reference physical resource blocks, the resource indication of the first level may adopt a bit table to represent all the resource sub-bands. When the resource sub-bands are located in overlapped frequency-domain reference physical resource blocks, the resource indication of the first level may use separate bit tables to represent different resource sub-bands.

The two-level resource indication manner may achieve compatibility of resources with different subcarrier spacings, and is universal and simple.

The total number of bits used by the two-level resource indication manner may be summarized as follows. If there are N frequency-domain reference resource blocks (corresponding to a frequency-domain reference subcarrier spacing f) in the system bandwidth, a resource configuration for the present terminal device includes K resource sub-bands corresponding to subcarrier spacings f₁, f₂, . . . f_(k) respectively, the numbers of physical resource blocks corresponding to each resource sub-band in each frequency-domain reference resource block are M₁, M₂, . . . M_(k) respectively, a bit table used for the first level requires N bits and the total number of bits required by determination of starting and ending positions of each resource sub-band in the second level is Σ_(i) ^(K) 2 log₂(M_(i)). Therefore, the total number of required bits is N+Σ_(i) ^(K) 2 log₂(M_(i)).

In at least one embodiment of the disclosure, the position of the starting physical resource block in each resource sub-band on the frequency domain and the number of the physical resource blocks in each resource sub-band may also be directly indicated, or the position of the starting physical resource block in a certain resource sub-band on the frequency domain and the position of the corresponding ending physical resource block may also be indicated, such that the positions of the resource sub-bands in the frequency domain may be indicated.

Furthermore, a starting position of physical resource blocks of a certain resource sub-band may be determined by a position of a frequency-domain reference physical resource block including a starting physical resource block and a relative position of the starting physical resource block of the resource sub-band in the frequency-domain reference physical resource block. Similarly, an ending position of physical resource blocks of a certain resource sub-band may be determined by a position of a frequency-domain reference physical resource block including an ending physical resource block and a relative position of the ending physical resource block of the resource sub-band in the frequency-domain reference physical resource block.

Specifically, as illustrated in FIG. 5, the frequency domain is still divided by the frequency-domain reference physical resource block firstly, and then a starting position of a resource sub-band is determined. As illustrated in FIG. 5, physical resources allocated in the resource sub-band are started from the frequency domain corresponding to a kth frequency-domain reference physical resource block (assume that a starting pointer of the frequency-domain reference physical resource block is 0), and a starting offset in the kth frequency-domain reference physical resource block is n. If the frequency-domain reference physical resource block includes four physical resource blocks corresponding to the resource sub-band, an absolute pointer of the starting physical resource block is 4 k+n, and an allocated resource length 5 is the number of the physical resource blocks.

The total number of bits used by a direct indication manner is summarized as follows. If there are N frequency-domain reference resource blocks (corresponding to the frequency-domain reference subcarrier spacing f) in the system bandwidth, a resource configuration for the present terminal device includes K resource sub-bands corresponding to subcarrier spacings f₁, f₂, . . . f_(k) respectively, and the numbers of physical resource blocks corresponding to each resource sub-band in each frequency-domain reference resource block are M₁, M₂, . . . M_(k) respectively. Therefore, the total number of required bits is 2K*log₂(N)+Σ_(i) ^(K) 2 log₂(M_(i)).

Comparison of the numbers of the bits required in the two-level resource indication manner and in the direct indication manner may indicate that the difference lies in the first term. When N is relatively large and K is relatively small, the number of the bits required in the direct indication manner may be less than that required in the two-level resource indication manner. Otherwise, the number of the bits required in the two-level resource indication manner may be less than that required in the direct indication manner. For example, the whole system bandwidth is 80 MHz, when subcarrier spacings of frequency-domain reference resource blocks are set to be 60 kHz, there are 128 frequency-domain reference resource blocks on the frequency domain. If four resource sub-bands are allocated, resources of the first term required in the two-level resource indication manner are N=128>2*4*log(128) (resources of the first term required in the direct indication manner). However, if a width of a frequency-domain reference physical resource block on the frequency domain is 16*180 kHz=2,880 kHz, the whole 80 MHz bandwidth may include 32 frequency-domain reference physical resource blocks, and in such case, the resources of the first term required in the two-level resource indication manner are N=32<2*4*log(32) (the resources of the first term required in the direct indication manner). In general, for the two-level resource indication manner, when the number of the reference physical resource blocks is relatively small, fewer bits may be used for simultaneous allocation of multiple resource sub-bands with different carrier spacings to the same terminal; and for the direct indication manner, when the number of the reference physical resource blocks is relatively great, fewer bits may be used for allocation of multiple resource blocks with different carrier spacings to the same terminal.

In at least one embodiment, the resource configuration information may further include information for indicating the number of the resource sub-bands in resources presently allocated for the terminal device. For example, 3 bits may be used to indicate at most 8 resource sub-bands. It is to be understood that the resource sub-band in the embodiments of the disclosure may be formed by continuous physical resource blocks and may also be formed by multiple discontinuous physical resource blocks with the same subcarrier spacing. There are no limits made thereto in the embodiment of the disclosure.

It is to be understood that the technical solution of the embodiment of the disclosure is also applied to allocation of Virtual Resource Blocks (VRBs). The only difference is that the VRBs are mapped onto physical resource blocks according to some preset mappings after the VRBs are allocated according to the abovementioned method. In such a mapping manner, discrete resource allocation may also be implemented.
